Seriously though, if someone provides the solution to your homework you don't get any benifit. Come exam time are you plannig to try to use an iPhone (or similar) to upload photos of each question to rapidshare and ask on forums for people to get back to you with the answer?

I'd recommened getting practice at balancing the equations yourself. IMHO cheating in exams rarely works out well in the long term (see the Kobayashi Maru test for a fictional exception).
